Procrastination

Trying to do work right now feels like trying to punch through a brick wall (｡•́︿•̀｡)  Sometimes I do really well, where I will do lots and lots of work for a few days in a row, and really get through it all, but then I come to a standstill.. for weeks on end... I'm still doing my best but it's hard to get my brain to do things that it just doesn't feel like doing. It is in fact, near impossible. And yet I have to persevere, because this is my final semester of university, and I cannot afford to fail!! (╥﹏╥) Why is it so hard to just sit down and concentrate?!?! (＃`Д´)
